It is important to understand where abstractionism came from in order to understand what it is. It is believed that abstractism began around the year 1910, though it has roots in the late 1800s. Wassily Kandisky and Piet Mondrian are believed to be the pioneers of modern abstractism. Kandisky is given credit for the first modern abstract art. Abstract art depends on forms within the picture instead of pictorial representation. Cubism shows the first characteristics of abstractism, but is not classified as abstractism. According to Wikipedia abstractionism is influenced by impressionism, romantism, and expressionism. The abstractism of the twentieth century was impacted by post-impressionism.
Lots of digital abstract art is done in programs like Adobe Photoshope, which can be purchased and used by anybody. I think that is some of the appeal of this art anybody can learn to create it. The vibrant colors and unusual shapes appeal to the visual senses. This piece of art appears to be a spinning vortex. There is black and white lightening radiating out from the vortex. Black, white, and grey light is being absorbed by the vortex. As the vortex sucks in the lightening there are blue wisps of light being emitted from the vortex. The light that is being absorbed is cut into four sections like a four leaf clover.
